Active Aqua Air Pump, 4 Outlets, 6W, 15 L/min

Very low power

This is a average pump in terms of noise. I would not want to have this in my bedroom with output set at maximum, but it’s much quieter at lower output settings. The Whisper AP300 (my benchmark) is significantly quieter. I tested output by inverting a water filled gallon jug in a bucket and see how fast the air pump’s maximum output pushed all the water out. This is probably different than what the manufacturer uses to test output. Anyway, I calculated output to 9.5L per minute. In comparison the Whisper AP300 was 4 L per minute. These values were measured with all the output ports combined. Power consumption was 5 watts with complete free flow at max output and 3 watts when outputs were completely blocked; this is same as the AP300. Overall, good performing pump for the money. It also seems well built. I would buy again. Update 10/11/2023, this pump has been running continuously for the past 3 years and it’s still going strong with no sign of lower output or increase in noise. I’m impressed. Second update 4/21/2025, the same pump is still going strong with no drop in output. If anything, this pump has gotten quieter. Updating from 4 to 5 well deserved stars.

Excelente producto

Pros: Cheap, works well, adjustable flow (and noise). Cons: Power cord is EXTREMELY thin - susceptible to physical damage. The unit could be quieter but it is fairly quiet (to expect it to be quieter seems like asking 'too much' considering the good performance and great price. EDIT on full blast this unit is the quietest device in the room :) I HIGHLY recommend this unit. Once again I must say it is fairly quiet and I am extremely pleased.

Excelente, no hace ruido y pude conectar con llaves 12 miniacuarios de 2 litros

This is my second purchase of this pump. The 4 valves are great for air stones, sponge filters, etc. And it's very powerful, with a nob to adjust the amount of air. I'm using one for my 90 gallon (3 air bubbles, 1 sponge filter), the other for 2 aquariums, 2 valves for each! It's also a great price, especially for 4 valves (big Al's charges $70 plus). A 2 valve pump is $27 on amazon, and it's not REMOTELY as powerful (I've bought 2 different brands before giving up and buying this one again!) My only quibble is that they are loud. But, I'm guessing that in order to provide the power that this pump definitely has, it'll never be quieter?
